I have similar battery-life as filsd on full workload ( but my setup is very difficult to replicate on windows - different IDEs, and so on ).
However, on relatively idle load, min brightness with wifi on.
windows reads 5+, even 6+ hours on ( on first 10+ min. )
while ubuntu reads 4.75 hrs. max ( on first 10+ min. )
* I note first 10+ min. because once the fans start on ubuntu, even when idle, battery estimate goes down dramatically at less than 4 hrs.
